Title: Disposal of button type waste battery
Inventor: KARITA TETSUSABUROU
IPC: H01M6/52
Filed: 1980-07-29
Abstract: PURPOSE:To recover valuable material with low cost in a short time by impact- crusing a button type waste battery to remove a negative cap from a positive container after heat-treatment and separating and recovering powders in the container. CONSTITUTION:Plastics and rubber on a seal are burned by heat-treating a button type waste battery to loosen a negative cap, simultaneously hazardous gases such as mercury vapor generated in the negative electrode by heating are recovered and treated through another different process to make harmless, then a radial force is added with an striking-crusher such as a hammer-mill or an impact crusher to remove a negative cap from a positive container, and valuable material in the container are recovered by magnetic attraction and sieving. The seal is easily broken and mercury is almost evaporated and removed when the waste battery is heat-treated at a temperature near 600 deg.C. Because the negative cap is not magnetically attractive, it is preferably impact-crushed again after sieving. Thus valuable materials containing silver are recovered with a low cost and in a short time.

Title: Ball valve
Inventor: NAKADA TSUMORU
IPC: F16K5/06
Filed: 1986-05-07
Abstract: PURPOSE:To achieve a purpose without forming a groove in the seal member containing part of a body, by a method wherein a stopper ring is situated on the outer diameter side of a spring member or a projection is provided on the outer diameter side of the inner wall of the body. CONSTITUTION:The side opposite to a seat ring 1 side of a spring member 5 makes contact with an inner wall 7 of a body 20. The inner wall 7 of the body 20 has a projected inner wall surface 8, the outer diameter side of which is projected to the spring member side. The projected inner wall surface 8 makes contact with the seat ring 1 and serves as a stopper which prevents the occurrence of compressive deformation strain when an excessive compression load is applied on the spring member 5. Since the seat ring 1 is provided with a cylindrical projection, a body has a groove, and therefore a shape is simple. Instead of the projected inner wall surface 8, a different part, i.e. a stopper ring 9 may be used.
